I got this with the hope it would hold the Sennheiser XS Lav USB-C, and it does.
The cable is gripped pretty tightly, and I don't have a DPA lav mic to compare if it's too tight, but it hasn't caused issues yet with months of regular use. The mic fits inside the conical holder and doesn't fall out of place even when accidentally bumped.
The tiny rubber cable clip on the end of the bottom jaw is a clever way to provide strain relief and get the cable out of the way e.g. behind a shirt placket.
